Only about two hundred people a year attempt to hike the entire trail, taking about six months to complete it. Dave Odell thru-hiked in 1978 and in the same year Dan Torpey hiked from the NM/CO border to Mt Robson, Canada. German long-distance rider Günter Wamser (on his way from Tierra del Fuego to Alaska),[1] and Austrian Sonja Endlweber (who joined him for the rest of the journey from Mexico) managed to complete the tour with four Bureau of Land Managementmustangs in three summers 2007–09.[2]

In 2007, Francis Tapon became the first person to do a round backpacking trip "Yo-Yo" on the Continental Divide Trail when he thru-hiked from Mexico to Canada and back to Mexico along the CDT and needed 7 months to finish it.[3][4][5][6][7] This seven-month journey spanned over 5,600 miles.[8] Tapon took the most circuitous, scenic, high, difficult route north and while returning south, took the more expedient route.[9]Andrew Skurka completed the trail as part of the 6,875-mile Great Western Loop in 2007.[10]

The youngest person to hike the trail is Reed Gjonnes, who hiked the trail with her father Eric Gjonnes from April 15 to September 6, 2013 at the age of 13.[11][12]

The Crazy Cook Monument is the most commonly recognized starting or finishing point of the Continental Divide Trail, but due to its remote location, devoid of any lodging or other services, Columbus is considered a legitimate alternate starting or finishing point for those hiking or biking the CDT. Located 3 miles from the International Port of Entry at Palomas, Mexico, Columbus is a small border village with several amenities including two modest hotels, a gas station, a handful of small cafes, a US Post Office, a bank, auto mechanics, and grocery stores. Columbus is listed as an National Historic Landmark due to the invasion in 1916 by Pancho Villa and his "Villistas". The village has two museums and a state park commemorating Poncho Villa's raid and the so-called Punitive Mexican Expedition led by US Army General "Blackjack" Pershing, who attempted, but failed to capture him.

From the Crazy Cook Monument (the official southern terminus), the trail begins as a cross-country desire path; the official route up to Lordsburg will be surveyed based around this path at a future date.[16] From Columbus, the route is a roadwalk to Lordsburg.

The CDT passes through many of the highest and wildest mountain regions of Colorado, such as the San Juan Mountains in southern Colorado and the Sawatch Range in the central region. In most areas the trail is well marked. It is concurrent with the Colorado Trail for approximately 200 miles (320 km). The CDT itself meanders in Colorado some 650 miles (1,050 km) at higher altitudes. Depending on any given year’s snow-pack and a hiker’s individual schedule, alternative routes are available. The Creed Cut-off in the San Juan Mountains to avoid persistent snow or unfavorable weather is such an example. This should be balanced with Colorado's 'monsoon season' with afternoon thunderstorms that usually occur in late July and August. The route's location makes short side trips to many of Colorado's 14,000-foot (4,300 m) peaks feasible. A few stretches of the CDT in Colorado have no distinct marked or named trail, but Jonathan Ley's or Jim Wolf's maps are helpful.[17] The Continental Divide Trail in Colorado has been surveyed recently[when?] by Jerry Brown and colleagues.[18] Some stretches of the CDT in Colorado are still a wilderness footpath.

Lightning and hail storms come out of nowhere and with little warning in the Great Divide Basin of Wyoming; there is no place to hide.

Of all the five states traversed by the CDT, Wyoming has the most diverse terrain. This includes hiking through a large section of range-land in the middle of the state, known as the Great Divide Basin. Hikers must decide on a route with regard to the Great Divide Basin since the actual Continental Divide forks in southern Wyoming forming in an endorheic basin. The shortest route is through the middle where water availability is uncertain in most years. Further north the CDT traverses the mountainous 'bench' of the Wind River Range and then through the Absaroka Range in the northwest portion of the state. The grand finale is Yellowstone National Park where the CDT is routed from Yellowstone's southern back country, to Old Faithful and then exits west to Idaho.

Jack is not a thru hiker, but rather a Vietnam Vet who lived off of the grid for more than 20 years near Big Hole Pass in the Salmon-Challis National Forest. He chose this life style in part "to forget [his war experience]." Encountering the unexpected on the CDT is part of its allure.

The Montana portion of the CDT is almost entirely in mountain ranges, running along the Idaho border in the southern portion, before heading east toward Butte and north toward Glacier National Park via the Lewis and Clark National Forest and two National Wilderness areas. Approximately 110 miles (177 km) of the CDT traverses Glacier National Park.

The Montana Wilderness Association is the leading non-profit partner for the northern section of Continental Divide Trail. MWA staff are working to connect the 980 miles (1,580 km) of CDT in Montana and Idaho with the help of dedicated volunteers and agency partners.[20]
